me or I?: Usage Guide

Me is used in many constructions where strict grammarians prescribe I. This usage is not so much ungrammatical as indicative of the shrinking range of the nominative form: me began to replace I sometime around the 16th century largely because of the pressure of word order. I is now chiefly used as the subject of an immediately following verb. Me occurs in every other position: absolutely

who, me?

, emphatically

me too

, and after prepositions, conjunctions, and verbs, including be.

come with me
you're as big as me
it's me

Almost all usage books recognize the legitimacy of me in these positions, especially in speech; some recommend I in formal and especially written contexts after be and after as and than when the first term of the comparison is the subject of a verb.
